Exploring the Properties and Applications of Chemical Substance with CAS Number 26172-55-4

Understanding the Chemical Cas No. 26172-55-4

In the landscape of chemistry, the use of Chemical Abstracts Service (CAS) numbers is paramount for the identification and classification of chemical substances. Each CAS number is unique, serving as a universal identifier that simplifies communication about chemical compounds across various disciplines. The CAS number 26172-55-4 refers specifically to a compound known as 1,3-benzenedicarboxylic acid, diethyl ester, commonly recognized as diethyl phthalate (DEP).

Diethyl phthalate is a colorless, odorless, and viscous liquid that belongs to the family of phthalates, which are esters of phthalic acid. Its chemical formula is C12H14O4, and it has a molecular weight of about 222.24 g/mol. The structure of DEP includes two ethyl groups attached to a phthalate backbone, which is responsible for its properties and uses.

One of the defining characteristics of diethyl phthalate is its solubility. It is poorly soluble in water but highly soluble in organic solvents, making it an excellent candidate for applications that require compatibility with various organic compounds. DEP has a boiling point of approximately 295 °C and a melting point of -50 °C, further indicating its utility in different industrial applications.

Applications of Diethyl Phthalate

Diethyl phthalate is primarily used as a plasticizer, which is a substance added to plastics to enhance their flexibility, transparency, and durability. The compound is commonly found in personal care products, such as lotions, perfumes, and cosmetics, where it helps improve the texture and application properties. Additionally, diethyl phthalate is utilized in the production of polyvinyl chloride (PVC) plastics, inks, coatings, and adhesives.

The use of DEP in consumer products is not without controversy, as concerns over phthalates’ potential environmental and health impacts have been raised. As a result, regulations have been introduced in many countries to limit the use of certain phthalates in consumer items, particularly those designed for children, as phthalates can be endocrine disruptors.

Health and Safety Considerations

While diethyl phthalate is considered to have relatively low toxicity compared to other phthalates, exposure to large quantities can lead to health concerns. Animal studies have suggested potential reproductive and developmental effects associated with high doses. It is crucial for industries that use diethyl phthalate to follow the safety guidelines established by regulatory agencies such as the U.S. Environmental Protection Agency (EPA) and the European Chemicals Agency (ECHA).

In terms of occupational exposure, workers in manufacturing settings are advised to wear personal protective equipment (PPE) to mitigate inhalation or skin contact. Furthermore, proper ventilation systems should be implemented in workplaces handling diethyl phthalate to prevent the accumulation of vapors.

Environmental Impact

The environmental implications of diethyl phthalate also warrant discussion. As a concern in environmental chemistry, DEP can enter ecosystems through wastewater and can bioaccumulate in aquatic organisms. Hence, monitoring and managing its release into the environment is critical. Efforts are underway to explore safer alternatives to phthalates, particularly as the push for sustainable and eco-friendly products intensifies.

Conclusion

Diethyl phthalate, marked by the CAS number 26172-55-4, is a compound with diverse industrial applications, primarily as a plasticizer. Its chemical characteristics contribute to its widespread use in personal care products and plastics. However, with growing concerns about health risks and environmental impacts, the future of diethyl phthalate will likely involve stringent regulations and a move towards safer alternatives. Understanding the properties, uses, and implications of DEP is essential for scientists, manufacturers, and consumers alike, as we navigate the complexities of chemical safety and environmental stewardship in our modern world.
